One might criticise Horner that he is a sensitive fool or a sentimentalist fool,but the main point is that he composing great music,and he is doing so in a unique personal style which cannot be confused to any other composers' style.No wonder he is one of the most succesful composers who is currently working:he always has a great effect on your emotions.Just like John Barry,he is also thought that every music has to be a connection with the human soul,and make people think about the message of the music.The Beautiful Mind is also follows this rules:it wants to make us think about our humanity,or the meaning of our true human nature.And it has a message:all humans can commit mistakes(here the main character is so obsessed with mathematics that he almost loses all connection with reality),because commiting mistakes is part of the human nature,but in time we can find something which is capable to help us show the real way which is worthy to be followed,and the really important things in life (here,this thing is love).
The music captures the message of the film with its wonderful women choir,strings and piano and brasses,and some parts of it are moving to illustrate the dynamism of thinking(A Kaleidoscope Of Mathematics),and other parts of it are haunting and dramatic to illustrate the fact that the main character losing connection with reality/real world(Nash Descends Into Parcher's World) or relaxing to illustrate that the love of the main character wants to show him the way into reality,wants to show him that it is worthy to live in the real world,and meaningless to refuse it(First Drop-Off - First Kiss).
